Abstract
Method for treating golf ball surface which is made of balta resin, thermoplastic elastomer, ionomer resin or the like to unpolymerizable gas plasma and then applying usual coating in an apparatus adapted to expose the all over surface of the ball to said plasma. Owing to this treatment, exfoliation of the ball coating can unexpectedly sufficiently be prevented.
